Russia captures the entirety of Kostyantynivka by March 31, 2027.
Assesses whether Russian forces achieve full territorial control of the municipality of Kostyantynivka in Donetsk Oblast, as mapped by the ISW, by March 31, 2027.
Across 6 frontier models answering independently, the panel thinks this is unlikely: the median is 29%.
They do not agree: GPT puts it at 57% and DeepSeek at 18%, 39 points apart. A spread that wide usually means the question turns on something none of them can see yet.

It turns on whether Russia can convert pressure around the Slovyansk–Kramatorsk axis into a rapid urban encirclement before spring 2027.
- Russia must clear Ukrainian defenses west of Toretsk and along approaches to the city, then occupy every mapped municipal polygon by March 31.
- Large defended Donetsk cities have usually taken months or stalled; full-map capture is harder than reaching outskirts or claiming the city center.
- I would raise this sharply if Russian forces sever the Kramatorsk–Kostyantynivka supply corridor or establish a durable salient west of the city by early 2027.

Hinges on whether Russian forces can complete encirclement/urban assault on Kostyantynivka within the ~16-month window.
- Russian forces have been grinding toward Kostyantynivka for over a year with slow, incremental gains amid Ukrainian fortified defense.
- Historical pace of Russian advances on fortified Donbas cities (Bakhmut, Avdiivka) took 6-12+ months per city even after encirclement began, and Kostyantynivka is…
- A sudden collapse of Ukrainian lines in the Druzhkivka-Kostyantynivka-Kramatorsk agglomeration or a ceasefire/peace deal would most change this probability.

Turns on whether Russian forces have already reached Kostyantynivka's outskirts by Nov 2026 and can sustain urban assault tempo through winter.
- Russian advances in Donetsk have averaged 2-5 km/month against fortified lines; Kostyantynivka is a prepared defensive node comparable to Chasiv Yar, which took 10+…
- Capturing an entire municipality requires clearing urban blocks, not just reaching the edge—Avdiivka's full capture took ~4 months after encirclement was nearly complete.
- A collapse of Ukrainian manpower or a breakthrough on the T0504 corridor would sharply raise this; continued attritional pace keeps it below base rate for city captures…

Russian winter offensive must close remaining distance and finish urban fight in 4.5 months.
- ISW maps as of Nov 2026 still show Russian forces 8-15 km short of the municipal boundary after slow 2025-26 gains.
- Urban capture of comparable Donetsk cities (Bakhmut, Avdiivka) required 4-10 months of grinding once outskirts were reached.
- Ukrainian fortress-belt defenses and weather would have to collapse unusually fast for full shading by 31 Mar 2027.

Capturing Kostyantynivka requires taking Chasiv Yar first, leaving under five months of fighting to clear a major fortified city.
- Russian forces remain stalled on the eastern approaches and Chasiv Yar canal, making breakthrough by early 2027 improbable.
- Urban assaults against fortified Donbas agglomerations historically demand six to twelve months once city boundaries are reached.
- A rapid collapse of Ukraine's western Donetsk line or an abrupt ceasefire would materially swing these odds.

Whether Russia can finish clearing a fortified Donbas city it has not yet fully entered within 16 months.
- Russia has been grinding toward Kostyantynivka since mid-2025 but ISW shows the city's western and northern edges still contested as of November 2026.
- Urban clearing of a fortified city this size has taken Russia 6-12 months each time (Avdiivka, Bakhmut, Pokrovsk axis), and Kostyantynivka's urban core has barely been…
- The binding constraint is force generation and whether Russia prioritizes this axis versus Pokrovsk/Kupyansk; a Ukrainian collapse elsewhere would most change the odds.

Resolution criteria
This market will resolve to “Yes” if, according to the ISW map, Russia captures the entirety of Kostyantynivka, Donetsk Oblast, (48.528896° N, 37.702514° E) between market creation and the specified date, 11:59 PM ET. Kostyantynivka will be considered captured if the entirety of the municipality is shaded under a below specified layer on the ISW map (https://storymaps.arcgis.com/stories/36a7f6a6f5a9448496de641cf64bd375) by the resolution date. Otherwise, the market will resolve to “No”. The boundaries of the municipality are those shown under the “Ukrainian Settlements” layer on the ISW map. If all area within the municipality is shaded under a qualifying layer, however, the shading does not precisely match up with the border such that there is a tiny amount of unshaded area along the border of the municipality, this will still qualify for a "Yes" resolution. For any change on the ISW map to qualify for this market’s resolution, the relevant shading must persist through the next full ISW daily update cycle. If ISW skips a day, shading must persist until the next finalized ISW update is published, regardless of the date. Any continuous shading under the following layers will qua
